Configure the SIP proxy for network outage detection
When SIP traffic and the high availability (HA) manager traffic are not on the same network, failures that affect SIP traffic might not be detected by the HA manager, resulting in loss of SIP traffic. We can configure network outage detection on the same network as the SIP traffic to ensure that failures that affect SIP traffic can be detected by the HA manager.
Define these settings for network outage detection to ensure that SIP network failures are detected by the HA manager.
- From the console, select Servers > Server Types > WebSphere proxy servers > proxy_server_name > SIP proxy settings. Scroll to the SIP network outage detection settings on this page.
- Select Enable SIP network outage detection and enter the Keep alive interval. The proxy will send keep alive messages to the server at the configured keep alive interval.
- Specify the Maximum keep alive failures to send before a server failure response is sent.
- Optional: Set the numFailuresSipAdvisorRequests custom property so that the SIP proxy notices the failure to receive load balancer advisor requests.
Results
If the proxy misses the number of responses configured as keepAliveFailures, or the server misses that number of keep alive requests, it will determine that SIP traffic should no longer be sent between the proxy and the server. The proxy will stop sending SIP messages to that server, and the server will restart and wait for connectivity to be restored before resuming operation.
